This paper deals with the anti-synchronization issue for stochastic delayed reaction-diffusion neural networks subject to semi-Markov jump parameters. A resilient fault-tolerant controller is utilized to ensure the anti-synchronization in the presence of actuator failures as well as gain perturbations, simultaneously. Firstly, by means of the Lyapunov functional and stochastic analysis methods, a mean-square exponential stability criterion is derived for the resulting error system. It is shown the obtained criterion improves a previously reported result. Then, based on the present analysis result and using several decoupling techniques, a strategy for designing the desired resilient fault-tolerant controller is proposed. At last, two numerical examples are given to illustrate the superiority of the present stability analysis method and the applicability of the proposed resilient fault-tolerant anti-synchronization control strategy, respectively.
本文针对时滞随机反应扩散神经网络的反同步问题进行了研究,该网络的参数具有半马尔可夫跳变特性。利用弹性容错控制器同时确保了在执行器故障和增益摄动情况下的反同步。首先,通过李雅普诺夫泛函和随机分析方法,得到了误差系统的均方指数稳定性判据。结果表明,所得判据改进了已有文献的结果。然后,基于该分析结果并采用几种解耦技术,提出了一种设计所需弹性容错控制器的策略。最后,通过两个数值例子分别说明了所提出的稳定性分析方法的优越性和弹性容错反同步控制策略的适用性。
